The correct replacement for Tempstar model T4H330GKB200 — 1-Pole 30A 24V Coil | Ships Today is this exact part. It is the factory-specified replacement with exact OEM specifications.

My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Is this contactor compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

This is the genuine OEM definite-purpose contactor (part number 1172472) for the Tempstar T4H330GKB200 heat pump. A contactor is the electromechanical relay that switches high-voltage line power to the compressor and condenser fan motor whenever the 24V control signal from the thermostat or defrost board energizes its coil. This is a 1-pole, 30-amp unit with a 24V coil and an integrated shunt. When a contactor fails, the outdoor unit either won't start (no pull-in) or won't shut off (welded contacts), both of which strand the system in a non-cooling or non-heating state.

Compatibility

Installation Guide

Access — Remove the condenser service/electrical panel.
Document — Photograph all line and 24V control wires before disconnecting.
Remove — Note terminal positions, transfer wires one at a time off the old contactor, and unbolt it from the bracket.

Test — Restore power and confirm the contactor pulls in on a call and drops out cleanly when satisfied.
